TECHNICAL INNOVATIONS
" It's imperative hydrogen
IC engines are accepted as
a ZEV solution to enable
swifter uptake of zerocarbon
solutions. "
- Peter Müller-Baum, VDMA
Deutz's first hydrogen engine, the TCG 7.8 H2, is currently running in a generator application and will
be transferred to an 18-tonne truck.
a refueling time of five minutes, the
companies claim.
Volvo Trucks also recently announced
it will begin testing hydrogen fuel-cell
electric trucks in commercial applications
in northern Europe in 2025. Each
of the trucks will use two 300-kW fuel
cells supplied by cellcentric, a jointventure
company established by Volvo
Group and Daimler Truck AG.
According to Jessica Sandström, senior
VP, global project management at
Volvo Trucks, " The tests will run in a demanding,
harsh climate and it will also
give us a great opportunity for driving
with heavy loads up to 65 tonnes. "
In the U.S., Toyota Motor North
America and Kenworth announced in
September that they completed the
demonstration of the capabilities of the
Toyota-Kenworth T680 fuel-cell electric
vehicle in the Zero- and Near-Zero
Emissions Freight Facilities (ZANZEFF)
" Shore to Store " project at the Port of
Los Angeles, the Los Angeles basin and
the Inland Empire.
The ten Kenworth Class 8 semi-tracHYVIA's
hydrogen-powered commercial vehicle was on display at the 2022 IAA Transportation
show. The company also has bus and chassis-cab versions of the vehicle.
combustion engines. Deutz has developed
a 7.8-L hydrogen engine that is
currently running in a generator application
and will be transferred to an
18-tonne truck. Volvo Group and KEYOU
are developing a 13-L engine for use in
40-tonne trucks. The vehicles will be
used in logistics applications to determine
viability.
Fuel-cell projects
Recent hydrogen-fuel projects include
HYVIA, a joint venture between Renault

Group and Plug, a European supplier of
hydrogen creation and distribution. At
the 2022 IAA show, HYVIA exhibited a
" platform play " that included three of
its commercial vans, the Master Van
H2-TECH, Master City Bus H2-TECH and
the Master Chassis Cab H2-TECH. The
van version, for example, has a loading
volume of 423.8-cu-ft (12.0-cu-m). Its
30-kW fuel cell, 33-kWh battery and 6
kg (13.2 lb.) of hydrogen - stored in
four 1.5-kg (3.3-lb.) tanks - provide a
range of up to 310 miles (499 km) and
tors, powered by Toyota hydrogen fuel
cells, have a load capacity of 82,000 lb.
GCWR (37,194 kg) and proved they are
capable of traveling approximately 300
miles (482 km) with the load. Importantly
the trucks, which were operated in the
project by actual companies including
Toyota Logistics Services, could be refueled
in 15 to 20 minutes (see related article:
www.sae.org/news/2022/09/toyota-hydrogen-fuel-cell-powertrain).
Assuming
that the long-promised,
battery-electric Tesla Semi enters production,
its recharging time will certainly
be longer than 20 minutes. In the
commercial trucking business, time on
the road is money.
